DC3122A

DC3122A is a demonstration circuit 3122A featuring the LTC®3307A 5V, 3A synchronous step-down Silent Switcher® operating as a 2MHz, 3.3V to 1.2V 3A buck regulator. The LTC3307A supports adjustable output voltages from 0.5V to VIN with operating frequencies from 1MHz up to 3MHz. The LTC3307A is a compact, ultralow emission, high efficiency, and high speed synchronous monolithic step-down switching regulator. A minimum on-time of 22ns enables high VIN to low VOUT conversion ratios at high frequencies. The DC3122A also has an Electromagnetic interference (EMI) filter to reduce conducted EMI. This EMI filter can be included by applying the input voltage at the VIN EMI terminal.

• 2.25 to 5.5V input voltage range at TA = 25°C;
• 22ns top switch minimum on-time
• 100% top switch duty cycle
